When the repeal is complete, critics say Internet-service providers could slow down connections to content they don’t like.

A common example is an ISP blocking a user’s access to another ISP’s Web site so they can’t sign up for a competing service.

Interest in NYC Mesh has skyrocketed since the FCC’s decision, Hall said.

“We’d normally get 20 requests a month to join, and in December, we got 438,” he said. “It’s continued like that.”

The group’s current main antenna is a 90-foot-tall “supernode” that stands in downtown Manhattan and connects to the Internet.

The supernode broadcasts an Internet connection out about two miles. NYC Mesh members pick up the signal through a “node’’ on their roofs.

Each user node is approximately the size of a satellite-TV dish.

Those smaller nodes also act as repeaters that forward the supernode’s signal beyond its radius, so each user is effectively increasing the network’s range farther and farther from lower Manhattan.

Still, major ISPs deny that they have any plans to interfere with customers’ Internet access.

In a statement to The Post, Spectrum said, “We don’t slow down, block, or discriminate against lawful content.” A Verizon spokesman said, “Nothing has changed, and we have no intent to do anything differently.”
